Function QueryParams

binder_generic.go:164–175

QueryParams extracts and parses all values for a query parameter key as a slice. It returns the typed slice and an error if binding any value fails. Returns ErrNonExistentKey if parameter not found. See ParseValues for supported types and options

(c *Context, key string, opts ...any)

//
// See ParseValues for supported types and options
func QueryParams[T any](c *Context, key string, opts ...any) ([]T, error) {
	values, ok := c.QueryParams()[key]
	if !ok {
		return nil, ErrNonExistentKey
	}

	result, err := ParseValues[T](values, opts...)
	if err != nil {
		return nil, NewBindingError(key, values, "query params", err)
	}
	return result, nil
